Autolamp System

The optional autolamp system offers automatic, light-sensitive control of the headlamps. The system allows headlamp activation in low light conditions and deactivation in adequate light conditions. The system also provides increased visibility when leaving the vehicle, with the ignition switch in the OFF position, by providing a delay before the headlamps turn off.

The headlamp switch overrides the autolamp system. For the autolamp system to operate, the headlamp switch must be rotated to the first position (OFF).

The autolamp system consists of the following components:
- Autolamp module.
- Autolamp switch.
- HEADLAMP RH relay.
- HEADLAMP LH relay.
- A/LIGHT (H/L) relay (Autolamp headlamp).
- A/LIGHT(TAIL) relay (Autolamp tail lamp).
- Photo diode.

The photo diode is located in the instrument panel upper moulding on the right side of the instrument panel near the lower right corner of the windshield glass. When activated, the photo diode senses light conditions outside the vehicle and turns the headlamps on or off.

The autolamp switch is located just above the headlamp switch. The autolamp switch is incorporated with the autolamp/light switch rheostat resistor and activates the autolamp system when rotated to the right. The autolamp switch allows the operator to adjust the time the headlamps remain on after turning the ignition switch to OFF. The autolamp switch will leave the headlamps on a minimum of five seconds and a maximum of three minutes. The farther the autolamp switch thumb wheel is rotated to the right, the longer the delay will be.







The autolamp headlamp (AUTO LIGHT HEADLAMP) and LH headlamp (HEAD LAMP LH) relays are located in the engine compartment in the RH relay panel. The RH headlamp relay (HEAD LAMP RH) is located in the engine compartment in the main fuse junction panel. The tail lamp relay is part of accessory relay #2 located in the interior fuse junction panel.

The autolamp module s located to the right of the glove compartment and is mounted to the instrument panel support. The autolamp module receives inputs from the autolamp switch and the photo diode to control the operation of the autolamp system.
